BACKGROUND OF THE INVENTION

The present invention relates to the discovery of a new and distinct cultivar of northern highbush blueberry hybrid known as a Vaccinium corymbosum hybrid and referred to as ‘ZF06-079’, as herein described and illustrated.

The new blueberry plant variety ‘ZF06-079’ was selected in Lowell, Oreg., in 2006. ‘ZF06-079’ is an ornamental variety intended for nursery, landscape, and home garden use. The new variety has striking blue/green foliage with pink new growth throughout spring and summer and turns an attractive lavender color in the fall. The new variety ripens in mid-July and produces mildly sweet berries in loose clusters. The plant is vigorous, with an estimated chilling requirement of 500 hours.

The new blueberry plant originated from a cross of ‘Toro’ (female parent, unpatented) by ‘FLX-2’ (pollen parent, U.S. Plant Pat. No. 19,381). The female parent was produced by a cross between ‘Earliblue’ (unpatented) and ‘Ivanhoe’ (unpatented). The pollen parent was produced by a cross between ‘FL92-9’ (unpatented) and ‘Sunshineblue’ (unpatented). The new blueberry plant variety ‘ZF06-079’ has been planted in replicated trials since 2007.

The new variety differs from the unpatented female parent ‘Toro’ in that ‘ZF06-079’ has smaller leaves, is smaller in size, and has pronounced pink and red new growth.

‘ZF06-079’ differs from the patented male parent ‘FLX-2’ in that ‘ZF06-079’ is smaller in size and has more pronounced pink and red new growth.

The new blueberry plant variety ‘ZF06-079’ has maintained its distinguishing characteristics throughout successive asexual propagations. The variety has been repeatedly asexually reproduced through softwood cuttings in Lowell, Oreg., and the clones are phenotypically identical to the original plant.

SUMMARY OF THE INVENTION

The new blueberry plant variety ‘ZF06-079’ has not been observed under all possible environmental conditions. The phenotype may vary somewhat with variations in environment and cultural practices, such as temperature and light intensity, without any variance in genotype.

The following traits have been repeatedly observed in Lowell, Oreg., and are determined to be the unique characteristics of the new blueberry plant variety ‘ZF06-079’:

-   -   1. Striking blue/green foliage with pink new growth;     -   2. Lavender fall foliage;     -   3. Compact growth habit.

BOTANICAL DESCRIPTION

The following detailed description sets forth the distinctive characteristics of ‘ZF06-079’. The data which define these characteristics were collected from asexual reproductions of the original selection. Dimensions, sizes, colors, and other characteristics are approximations and averages set forth as accurately as possible. The plant history was taken on plants approximately three years of age, and the descriptions relate to plants grown in the field in Lowell, Oreg. Color designations are from The Pantone Book of Color (by Leatrice Eiseman and Lawrence Herbert; Harry N. Abrams, Inc., Publishers, New York, 1990). Where the Pantone color designations differ from the colors in the photographs, the Pantone colors are accurate.
